2011-01-23kvm: Stop on all fatal exit reasonsJan Kiszka
Ensure that we stop the guest whenever we face a fatal or unknown exit reason. If we stop, we also have to enforce a cpu loop exit. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2011-01-23kvm: x86: Swallow KVM_EXIT_SET_TPRJan Kiszka
This exit only triggers activity in the common exit path, but we should accept it in order to be able to detect unknown exit types. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2011-01-21kvm: x86: Prevent sign extension of DR7 in guest debugging modeJan Kiszka
This unbreaks guest debugging when the 4th hardware breakpoint used for guest debugging is a watchpoint of 4 or 8 byte lenght. The 31st bit of DR7 is set in that case and used to cause a sign extension to the high word which was breaking the guest state (vm entry failure).

2011-01-21kvm: x86: Remove obsolete SS.RPL/DPL aligmentJan Kiszka
This seems to date back to the days KVM didn't support real mode. The check is no longer needed and, even worse, is corrupting the guest state in case SS.RPL != DPL. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-01-21kvm: x86: Fix DPL write back of segment registersJan Kiszka
The DPL is stored in the flags and not in the selector. In fact, the RPL may differ from the DPL at some point in time, and so we were corrupting the guest state so far. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-01-21kvm: introduce kvm_inject_x86_mce_onJin Dongming
Pass a table instead of multiple args. Note: kvm_inject_x86_mce(env, bank, status, mcg_status, addr, misc, abort_on_error); is equal to: struct kvm_x86_mce mce = { .bank = bank, .status = status, .mcg_status = mcg_status, .addr = addr, .misc = misc, }; kvm_inject_x86_mce_on(env, &mce, abort_on_error); Signed-off-by: Hidetoshi Seto <seto.hidetoshi@jp.fujitsu.com> Signed-off-by: Jin Dongming <jin.dongming@np.css.fujitsu.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2011-01-21Add function for checking mca broadcast of CPUJin Dongming
Add function for checking whether current CPU support mca broadcast. Signed-off-by: Jin Dongming <jin.dongming@np.css.fujitsu.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2011-01-21Add "broadcast" option for mce commandJin Dongming
When the following test case is injected with mce command, maybe user could not get the expected result. DATA command cpu bank status mcg_status addr misc (qemu) mce 1 1 0xbd00000000000000 0x05 0x1234 0x8c Expected Result panic type: "Fatal Machine check" That is because each mce command can only inject the given cpu and could not inject mce interrupt to other cpus. So user will get the following result: panic type: "Fatal machine check on current CPU" "broadcast" option is used for injecting dummy data into other cpus. Injecting mce with this option the expected result could be gotten. Usage: Broadcast[on] command broadcast cpu bank status mcg_status addr misc (qemu) mce -b 1 1 0xbd00000000000000 0x05 0x1234 0x8c Broadcast[off] command cpu bank status mcg_status addr misc (qemu) mce 1 1 0xbd00000000000000 0x05 0x1234 0x8c Signed-off-by: Jin Dongming <jin.dongming@np.css.fujitsu.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2010-10-20MCE: Relay UCR MCE to guestMarcelo Tosatti
Port qemu-kvm's commit 4b62fff1101a7ad77553147717a8bd3bf79df7ef Author: Huang Ying <ying.huang@intel.com> Date: Mon Sep 21 10:43:25 2009 +0800 MCE: Relay UCR MCE to guest UCR (uncorrected recovery) MCE is supported in recent Intel CPUs, where some hardware error such as some memory error can be reported without PCC (processor context corrupted). To recover from such MCE, the corresponding memory will be unmapped, and all processes accessing the memory will be killed via SIGBUS. For KVM, if QEMU/KVM is killed, all guest processes will be killed too. So we relay SIGBUS from host OS to guest system via a UCR MCE injection. Then guest OS can isolate corresponding memory and kill necessary guest processes only. SIGBUS sent to main thread (not VCPU threads) will be broadcast to all VCPU threads as UCR MCE. aliguori: fix build Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
